Purpose:Illustrates centripetal force and that instantaenous velocity is tangent to the circular path
Description:A small glob of putty is stuck to the edge of a rotating disc. As the angular velocity is increased, at some point the force holding the putty will no longer be sufficient to provide the necessary centripetal force, and the putty leaves the rotating disc, moving tangentially away from the point of release.
This is a purely qualitative demonstration; to make measurements, try D1-35.
